Disappointed

this is the 1st time i feel deeply disappointed with someone.
i never expects much from him since i know i wont get what i want, but why cant him just fulfill my simple needs. honestly, its really just simple needs.
everytime when i need him, he is not by my side as he is suppose to do it but others ppl do. did he know how much i need him especially when i feel helpless? thanks for those ppl who lent there hand for me.
i feel tired n angry+disappointed with him, but i dun hate him. but im not sure the day will come in the future day. hopefully it wont happend.
